S-92311A934 3/8"-24 x 5/16" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
• Maximum torque transmission via the 3/16" hex drive, preventing tool slippage and ensuring secure fastening.
• Precise and secure thread engagement with Class 3A UNF fine threads, minimizing the risk of loosening under vibration.
• Excellent grip and component retention provided by the cup point tip, which bites into the mating surface.
• High mechanical strength and durability from Rockwell B80 hardness, resisting wear and deformation.
• Space-saving headless design for applications where a flush or low-profile installation is required.
• Guaranteed quality and interchangeability through compliance with the ASME B18.3 standard.

Professional Applications & Engineering Value

This 18-8 stainless steel set screw is engineered to solve critical challenges in industrial assembly and precision machinery. Its headless, hex drive design allows for high-torque installation in confined spaces, while the Class 3A UNF fine thread ensures a tight, vibration-resistant fit crucial for dynamic loads. The cup point creates a permanent indentation on the shaft, providing superior resistance to rotational forces and preventing component slippage in pulleys, gears, and couplings. Made from corrosion-resistant 18-8 Stainless Steel, it delivers long-term performance in demanding environments, from food processing equipment to marine applications, reducing maintenance needs and downtime.
